Among the fruits, bananas were found to be especially protective. Women eating bananas four to six times a week cut their risk of kidney cancer by 50% compared to those who did not eat bananas.

Bananas also contain compounds known as protease inhibitorswhich help eliminate bacteria in the stomach that are the primary cause of stomach ulcers.
